Ceh Pech (pronounced Keh Pech, 'Ceh (deer): patronymic, perhaps Ah Ceh; Pech (tick), perhaps also a patronymic composed of the union of two family names') is the name of a post-classic Maya ruling family and a province, or kuchkabal of the northern Yucatán Peninsula.
It existed before the Spanish conquest of the Yucatán in the 16th century. The Pech family exists to the present day.
The socio-political dissolution of the League of Mayapan occurred in the mid-15th century, before the arrival of Europeans. 16 jurisdictions ended, who occupied the territory now comprised by the Mexican states of Yucatán, Campeche, and Quintana Roo
Naum Pech is considered to be the founder of the dynasty. He was a relative of the Cocomes dynasty of Mayapan and reigned as the Halach Uinik from 1470 in Motul (now in the Mexican state of Yucatán), the capital of the principality that was named after his family: Ceh Pech.
Other members of the family's lineage of the Pech appeared in other locations such as: Tunal Ah Pech and their children, who settled in Maxtunil, Ah Kom Pech, seated in Xulcumcheel, Nakuk Pech, the batab of Chicxulub Pueblo. Ah Makam Pech, batab of Yaxkukul, and other relatives played leadership roles in the region.
Similar to the Tutul Xiu, the Ceh Pech cooperated early on, although not consistently, with the Spanish conquistadores. At times the Ceh Pech even provided auxiliary troops against principalities of the free Maya, pursuing traditional local policies of enmity. Nevertheless, their capital was conquered in 1538 and they lost their sovereignty. However, the Ceh Pech received recognition of their nobility by the Spanish and were allowed to carry the title of Don, usually reserved for the head of the family. In addition, the family retained their inherent economic and social supremacy over their former estates.
